I can not supply you with anything other than my executable and a description of how to reproduce the problem. This is with gdb v 7.8.1 running on my beagleboard xm under gentoo (arm cortex-a7 processor but cortex-m4 code) i woluld have no objections to sending you my sources if that helps On Mon, Dec 29, 2014 at 4:03 AM, Mark Manning wrote: > actually now I cant reproduce it, my GDB must have been in an insane state > when I posted the bug, it would not allow me to set any breakpoint on any > address unless it was 32 bit aligned.... now it will ! > > > On Mon, Dec 29, 2014 at 12:04 AM, dje at google dot com < > sourceware-bugzilla@sourceware.org> wrote: > >> https://sourceware.org/bugzilla/show_bug.cgi?id=3D17768 >> >> --- Comment #3 from dje at google dot com --- >> Sorry, "repro" =3D=3D "reproduction". >> >> How do I recreate the problem? >> Be as explicit as possible, don't leave anything out. >> e.g., what test program can I use? >> Got a complete transcript of a gdb session that shows the problem? >> etc. etc. etc. >> >> -- >> You are receiving this mail because: >> You reported the bug. >> > > > > -- > =E2=80=9CWhen something can be read without effort, > great effort has gone into its writing.=E2=80=9D > > =E2=80=95 Enrique Jardiel Poncela =E2=80=95 > --=20 You are receiving this mail because: You are on the CC list for the bug. >>From gdb-prs-return-17222-listarch-gdb-prs=sources.redhat.com@sourceware.org Mon Dec 29 13:16:53 2014 Return-Path: Delivered-To: listarch-gdb-prs@sources.redhat.com Received: (qmail 810 invoked by alias); 29 Dec 2014 13:16:52 -0000 Mailing-List: contact gdb-prs-help@sourceware.org; run by ezmlm Precedence: bulk List-Id: List-Subscribe: List-Archive: List-Post: List-Help: , Sender: gdb-prs-owner@sourceware.org Delivered-To: mailing list gdb-prs@sourceware.org Received: (qmail 785 invoked by uid 48); 29 Dec 2014 13:16:51 -0000 From: "unavowed at vexillium dot org" To: gdb-prs@sourceware.org Subject: [Bug gdb/17771] New: Crash parsing symbol Date: Mon, 29 Dec 2014 13:16:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: new X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gdb X-Bugzilla-Component: gdb X-Bugzilla-Version: 7.8 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: unavowed at vexillium dot org X-Bugzilla-Status: NEW X-Bugzilla-Priority: P2 X-Bugzilla-Assigned-To: unassigned at sourceware dot org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_id short_desc product version bug_status bug_severity priority component assigned_to reporter Message-ID: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit X-Bugzilla-URL: http://sourceware.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2014-q4/txt/msg00465.txt.bz2 Content-length: 1491 https://sourceware.org/bugzilla/show_bug.cgi?id=17771 Bug ID: 17771 Summary: Crash parsing symbol Product: gdb Version: 7.8 Status: NEW Severity: normal Priority: P2 Component: gdb Assignee: unassigned at sourceware dot org Reporter: unavowed at vexillium dot org $ cat test.c int test __asm__ ("_Z16affine_transformIddLm2EE6VectorIDTmlcvT__EcvT0__EEXT1_EERK6MatrixIS1_XplT1_Li1EEXplT1_Li1EEERKS0_IS2_XT1_EE"); int main (void) { return 0; } $ gcc -o test test.c $ gdb ./test GNU gdb (GDB) 7.8 Copyright (C) 2014 Free Software Foundation, Inc.
